"Green Step conducted a very thorough energy audit, then performed approx. 1 and 1/2 days of work including attic insulation, extensive air sealing, and numerous related tasks. The owner was present for the work much of the time, and the work crew was hard working, efficient and did a great job cleaning up. We had a significant measured improvement in the follow-up test - 34%. We were very pleased will all aspects of their work."
